AC test load = 50 pF for XCF01S/XCF02S/XCF04S; 30 pF for XCF08P/XCF16P/XCF32P.
Float delays are measured with 5 pF AC loads. Transition is measured at ±200 mV from steady-state active levels.
Guaranteed by design, not tested.
All AC parameters are measured with V

The delay before the enabled CLKOUT signal begins clocking data out of the device is dependent on the clocking configuration. The delay
before CLKOUT is enabled increases if decompression is enabled.
Slower CLK frequency option might be required to meet the FPGA data sheet setup time.
Typical CLKOUT default (fast) period = 25 ns (40 MHz).
toggles at ½ the source clock frequency (either ½ the selected internal clock frequency or ½ the external CLK input frequency). When
decompressed data is not available, the CLKOUT pin is parked High. If CLKOUT is used, then it must be pulled High externally using a
4.7 kΩ pull-up to V
